The genetic relationships and molecular characteristics of 34 Bacillus anthracis isolates from soil in various regions of Korea and 17 related Bacillus species by using both the amplified fragment length polymorphism (AFLP) and multilocus variable-number tandem repeat (MLVA) approaches are analyzed. It indicates that MLVA markers on two plasmids loci and human activity influence differences in cluster prevalence and distribution more.

Characterization of a novel amyloytic enzyme encoded by a gene from a soil-derived metagenomic library

Article Abstract:

A metagenome is isolated from soil samples to isolate useful microbial enzymes from uncultured soil microorganisms and a metagenomic library is constructed by using the pUC19 vector. The hydrolysis and transglycosylation properties of putative amylase gene (amyM) suggest that it has novel characteristics and can be regarded s an intermediate type of maltogenic amylase, alpha-amylase and 4-alpha-glucanotransferase.

Impact of Bt corn on rhizosoheric and soil eubacterial communities and on beneficial mycorrhizal symbiosis in experimental microcosms

Article Abstract:

The impact of Bt 11 and Bt 176 corn plants and their residues on bulk soil and rhizospheric eubacterial communities on the arbuscular mycorrhizal fungus Glomus mosseae and on soil respiration are evaluated. Results reveal differences in rhizospheric eubacterial communities with the three corn lines and a significantly lower level of mycorrhizal colonization in Bt 176 corn roots.
